When I look at long fields in my columns in Mp3Tag, I see a "..." at the end of the field, but when I click on the field the rest of the tag will appear. So, the information is there, but it seems as if Mp3Tag has a limit on the amount of characters it will display in the column for that field. It seems odd that would be the case.
Please let me know if you think you know what is going on.
On a side note, I have searched and I am wondering if there is a limit to the amount of characters in a field. I seem to remember that m4a uses atoms that are limited to 255 characters to store its tags, but I am not sure if that is the case across all platforms and formats.
Is 255 the limit for characters in a field?
